Uses for Expired Milk

Posted on February 20, 2008 by Allie

We’ve talked about uses for expired yogurt and expired aspirin, but what about expired milk?

Depending on how it’s stored, milk can considered good for 3 to 7 days after the “sell by” date.  I don’t know about you, but about three days after the sell by date, I start to convince myself that the milk smells or tastes funny even when it probably doesn’t.  The University of Missouri State Extension Specialist for Food Safety says, “milk held past the expiration date may be clotted and smell, but it is almost certainly safe – just as yogurt and buttermilk is.”  But there are also many reports that say you shouldn’t consume expired milk as well.  You have to use your common sense and do what you’re comfortable with.

Some recipes (like this one for coffee cake) actually call for sour milk, and it’s widely believed that baking with expired milk is safer than drinking it.

A commenter on Thrifty Fun recommends pouring it down the toilet if you have a septic tank.  The enzymes will help break down the contents of the tank.

Much like yogurt, it’s a great addition to compost, and another Thrifty Fun commenter swears by watering roses with sour milk.

You could take a milk bath.

Or you could use it to make your own paint.

If you know you’re not going to use the milk in your fridge before the expiration date, freeze it in smaller quantities and use it as needed.

  1. I don’t let milk expire. I’m a growing boy, so I drink it. It’s good for building strong bones and a healthy smile.

  2. I use it in pancake batter or dilute it and sprinkle it on plants with powdery mildew.

  5. My milk seems to expire the exact day or even a day before the “sell by” date. I keep trying to adjust my fridge temp but it keeps happening. I mean, not just a sour smell but chunks even appear a day later. Do you think my grocer is selling old milk?

  7. I heard you can make wood glue from the clear liquid in sour milk and bee honey, by mixing the bee honey and clear liquid in equal parts example one cup of each. Has anyone else heard or tried this?

  8. The clear liquid in separated milk is called whey and there are so many uses for it, especially with cooking. :)

Tip of the Day

If It Doesn’t Smell, Don’t Wash It


According to Real Simple, if every American made an effort to launder less — cutting out just one load of laundry a week per household — we’d save enough water to fill seven million swimming pools each year.

So if it looks clean, and it smells clean, call it clean and wear it again. Consider hanging worn clothes out on your clothesline to freshen them up between wearings.
